P1191 KIA Meaning
The Electronic Throttle System (ETS) consists of an ETS unit, ETS motor, Accelerator Position Sensor (APS), Throttle Position Sensor (TPS), and a Limp Home Valve.
Among the parts mentioned above, the Limp Home Valve is mounted under the throttle body and helps air flow from the outside through this valve into the engine combustion chamber to prevent the vehicle from stalling when the Powertrain Control Module (PCM) detects a malfunction in the ETS system.
